Calculating Putts: PART I BASIC CALCULATIONS FOR STANDARD SPEED GREEN.
1. Watch the video on WGT on how to putt in order to learn how to adjust for left and right according to grade.
2. Subtract distance to hole from putter strength: Example: Putter Strength = 25 Distance to hole = 10 feet 25-10 = 15. new distance to hole.
3. Adjust rise/fall as noted on flag in inches. Be sure to look carefully: IE it could say 2 feet down. You must convert feet to inches. So 2 feet x 12 = -24 inches.
4. In This example we will be dealing with inches: we have a fall of five inches. -5 inches Now multiply rise/fall in inches x 1.3. So (-5) x1.3 = (-6.5).
5. New hole distance is 10 feet + (-6.5) or 10 - 6.5 = 3.3 feet to the hole.9NEW DISTANCE)
6. To determine the amount of strength to use, divide new distance to hole by putter strength EXAMPLE
3.3 divided by 25 = 13% of 25.
I WILL BE POSTING PART II SOON, HOW TO ADJUST FOR FAST AND VERY FAST. (Note: I prefer not to use slow greens)
